Replace and upgrade your VELUX glazing. 

Has your existing glazing reached the end of its life?.  Cloudy and misted glazing means the seal between the two panes has failed releasing the gas that helped reduce the transfer of heat.  This results in excess condensation and a non efficient window.  If your glazing is broken we can replace it along with a general service to the window.  If your window is over a certain age we can install a VELUX upgrade kit to allow it to accept a modern 24mm thick double glazed VELUX unit.  Read more.
